Editor Update Loop

[CornLizard]

Hello, I'm trying to use UniTask in the editor and when I call Await or SwitchTo it faults. Is UniTask supposed to work in the editor?

Edit: It only ever reaches and calls Debug.Log("0");

using UniRx.Async;
using UnityEngine;

[ExecuteAlways]
public class Test : MonoBehaviour
{
    private UniTask task;
    private bool isRunning;

    private void Start()
    {
        task = UniTask.Run(Update);
    }

    private async UniTask Update()
    {
        isRunning = true;
        while (isRunning)
        {
            Debug.Log("0");
            await UniTask.Yield();
            Debug.Log("1");
            await UniTask.SwitchToTaskPool();
            Debug.Log("2");
            await UniTask.SwitchToMainThread();
            Debug.Log("3");
        }
    }
    private void OnDestroy()
    {
        isRunning = false;
        task.GetAwaiter().GetResult();
    }
}
